Title: BPS-states and automorphic representations of exceptional groups
Abstract: Automorphic forms on exceptional Lie groups appear naturally in string theory compactifications. They manifest themselves as couplings in higher derivative corrections and in terms of generating functions of BPS-states. I will explain how to treat automorphic forms in the modern theory of automorphic representations, which can be directly connected to BPS-states in string theory. Various recent results, conjectures and open problems are outlined.
